Removing featured image from inside post

I’m using the Enfold theme and I like my featured image showing up in my grid on the main page. But when I click a post it opens up having the featured image scaled way up on the beginning of the post. I am inserting all the images I need myself in the post, so don’t need the featured image to appear again.

How do I remove this featured image on all single posts? I’ve been googling myself and I’ve read about removing some code in single.php but my single-file looks different than most others so can’t find the code people are talking about:

——————————————————-

<?php
global $avia_config;

/*
* get_header is a basic wordpress function, used to retrieve the header.php file in your theme directory.
*/
get_header();

$title = __(‘Blog – Latest News’, ‘avia_framework’); //default blog title
$t_link = home_url(‘/’);
$t_sub = “”;

if(avia_get_option(‘frontpage’) && $new = avia_get_option(‘blogpage’))
{
$title = get_the_title($new); //if the blog is attached to a page use this title
$t_link = get_permalink($new);
$t_sub = avia_post_meta($new, ‘subtitle’);
}

if( get_post_meta(get_the_ID(), ‘header’, true) != ‘no’) echo avia_title(array(‘heading’=>’strong’, ‘title’ => $title, ‘link’ => $t_link, ‘subtitle’ => $t_sub));

?>

<div class=’container_wrap container_wrap_first main_color <?php avia_layout_class( ‘main’ ); ?>’>

<div class=’container template-blog template-single-blog ‘>

<main class=’content units <?php avia_layout_class( ‘content’ ); ?> <?php echo avia_blog_class_string(); ?>’ <?php avia_markup_helper(array(‘context’ => ‘content’,’post_type’=>’post’));?>>

<?php
/* Run the loop to output the posts.
* If you want to overload this in a child theme then include a file
* called loop-index.php and that will be used instead.
*
*/

get_template_part( ‘includes/loop’, ‘index’ );

//show related posts based on tags if there are any
get_template_part( ‘includes/related-posts’);

//wordpress function that loads the comments template “comments.php”
comments_template( ‘/includes/comments.php’);

?>

<!–end content–>
</main>

<?php
$avia_config[‘currently_viewing’] = “blog”;
//get the sidebar
get_sidebar();

?>

</div><!–end container–>

</div><!– close default .container_wrap element –>

<?php get_footer(); ?>

So what to remove? If this is the right place to do it?

THANKS!!! 🙂

PS. A totally different topic: Is it possible to have a post open up in a lightbox instead of a new page? Would be very cool!
